empty string when call ImageIO.getReaderMIMETypes()

[CarolWu1206]

When jai-imageio-core is not included, the result for ImageIO.getReaderMIMETypes() is
"image/png","image/vnd.wap.wbmp","image/x-png","image/jpeg","image/bmp","image/gif".

After employing the package, the result is
"","image/png","image/vnd.wap.wbmp","image/jpeg","image/x-portable-graymap","image/bmp","image/pcx","image/x-windows-bmp","image/gif","image/x-windows-pcx","image/x-pc-paintbrush","image/x-bmp","image/x-pcx","image/x-png","image/x-portable-bitmap","image/x-portable-pixmap","image/tiff","image/x-portable-anymap".

The empty string in the head causes error, is it possible to remove such a string?

Thanks! The empty string seems to come from com.github.jaiimageio.impl.plugins.raw.RawImageReaderSpi

which has weirdly specified:

private static String[] entensions = {""};
private static String[] mimeType = {""};

i don't know which of the many "raw" formats this means, so I've changed those to extension raw and mimetype image/x-raw in RawImageReaderSpi and RawImageWriterSpi
